tools/nolibc: stdint: use __SIZE_TYPE__ for size_t
Otherwise both gcc and clang may generate warnings about type mismatches:
sysroot/mips/include/string.h:12:14: warning: mismatch in argument 1 type of built-in function 'malloc'; expected 'unsigned int' [-Wbuiltin-declaration-mismatch] 12 | static void *malloc(size_t len); | ^~~~~~
The compiler provides __SIZE_TYPE__ as the type that corresponds to size_t (typically "long unsigned int" or "unsigned int"). It was verified to be available at least since gcc-3.4 and clang-3.8, so from now on we'll use this definition for size_t.

selftests/nolibc: not include limits.h for nolibc

Glibc (>= 2.33) commit 5b6113d62efa ("RISC-V: Support the 32-bit ABI implementation") fixed up above error.
As suggested by Thomas, defining INT_MIN/INT_MAX for nolibc can remove the including of limits.h, and therefore no above error. of course, the other libcs still require limits.h, move it to the right place.
The LONG_MIN/LONG_MAX are also defined too.

tools/nolibc: add integer types and integer limit macros
This commit adds some of the missing integer types to stdint.h and adds limit macros (e.g. INTN_{MIN,MAX}).
The reference used for adding these types is https://pubs.opengroup.org/onlinepubs/009695399/basedefs/stdint.h.html.
We rely on the compiler-defined __LONG_MAX__ to get the right limits for size_t, intptr_t, uintptr_t and ptrdiff_t. This compiler constant seem to have been defined at least since GCC 4.1.2 and clang 3.0.0 on x86_64. It is also defined on ARM (32&64), mips and RISC-V.
Note that the maximum size of size_t is implementation-defined (>65535), in this case I chose to go with unsigned long on all platforms since unsigned long == unsigned int on all the platforms we care about. Note that the kernel uses either unsigned int or unsigned long in linux/include/uapi/asm-generic/posix_types.h. These should be equivalent for the plaforms we are targeting.
Also note that the 'fast*' flavor of the types have been chosen to be always 1 byte for '*fast8*' and always long (a.k.a. intptr_t/uintptr_t) for the other variants. I have never seen the 'fast*' types in use in the wild but that seems to be what glibc does.
